Koeman emphasised before last Sunday's 2-0 home win against West Ham that he wanted to see more support for top-scorer Romelu Lukaku, who netted one goal in the game to take his tally for the season to seven, as well as producing his third assist of the campaign.

And Mirallas told evertonfc.com ahead of Saturday's league trip to Chelsea: "Personally, I need to create more, score more goals and get more assists.

"It is not easy and we need the whole team to help each other so we can improve even more.

"I have spoken to the manager and he has told me I have been playing well but he wants more, and I agreed.

"I have looked at my game, looked at situations when I need to dribble more, or pass or shoot more.

"This week I have been training hard because we know it's another big game."

Mirallas has scoring form against Chelsea, having netted in the last two seasons against them, in the dramatic 3-3 draw at Stamford Bridge last term and the 6-3 home defeat in 2014-15.

He added: "If you score against the same team a couple of times, it is something that gives you confidence.

"And I like to play at Stamford Bridge. The stadium is nice, there is always a good pitch and our fans always create a very good atmosphere to support the team."

Sixth-placed Everton go into the 5.30pm kick-off against fourth-spotted Chelsea reinvigorated by the West Ham result, which halted their winless run.

"The win against West Ham has given us all a boost because we had not won in four games," Mirallas said.

"When you look at the table, you see we're in the European positions and close to the top, and w e need to continue into Saturday night now."

Goalkeeper Maarten Stekelenburg has recovered from a foot injury so is able to return to action after missing the West Ham game, in which Joel Robles deputised.

But defender Leighton Baines and midfielder James McCarthy remain unavailable due to hamstring problems.

Striker Arouna Kone (knee) is also not yet ready for action, and midfielder Idrissa Gueye will miss out as he serves a suspension.

On-loan forward Enner Valencia can make his comeback to the match-day squad after being ineligible last time out against parent club West Ham.

It remains to be seen whether Koeman restores captain Phil Jagielka to the team after dropping him to the bench and replacing him in central defence with Ramiro Funes Mori for Sunday's contest.
